Tabular Corundum
What is tabular corundum
Tabular corundum is a kind of pure sintered corundum that does not add any additives such as MgO, B2O3, and so on. It has a coarse and well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99%. . (According to the molecular structure, corundum can be divided into fine material, granular, flake, spherical, etc.)
Features
- high purity
- high whiteness
- low apparent porosity
- low water absorption

Application
Tabular corundum can be used as the main component in aluminum-carbon, aluminum-magnesium-carbon, magnesium-aluminum-carbon, magnesium spinel, aluminum-chromium refractory bricks; It can also be introduced into high-alumina amorphous refractory as a component of enriched alumina.
It can be widely used in steel, casting, ceramics and other industries, and its application in the steel industry covers almost the entire process of iron making and steelmaking.
Characteristics
High refractoriness, high corrosion resistance, high slag resistance, high thermal shock resistance, high strength, good toughness and chemical stability, high erosion resistance.
Packing information
Tons of bags. The net weight of a ton bag is 1 ton, and the height is 80 cm after being packed. A small cabinet can be placed on three layers and contains 25 bags. A ton bag weighs 3 kilograms.
